Electronic Map Mark Synchronization via Wireless Positioning Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS systems are limited to detecting only the user's position, making it difficult for one user to guide another to their location without both parties having GPS-enabled devices, leading to inefficient navigation.
Innovation Solution
A method for synchronizing marks on electronic maps between two devices, where a mark on one device is converted into positioning information and transmitted wirelessly to another device, allowing the mark to be reconstructed on the receiving device's map, including adjustments for scaling and center coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used to detect user position, then position detection capability is improved, but the system cannot detect others' positions without additional GPS devices
Solution Approach 1:
The patent creates a visual copy of the mark displayed on one device's screen and transmits it to another device. Instead of requiring the second device to have GPS capabilities, the system captures the visual representation of the location mark from the first device's display and reproduces it on the second device, enabling position sharing without additional positioning hardware.
Solution Approach 2:
The patent introduces an intermediary process that converts the GPS position data into a visual mark display, then captures and transmits this visual representation. The mark image serves as an intermediary carrier that bridges the gap between GPS-capable and non-GPS-capable devices, allowing position information to be shared universally.
2Adaptability or versatility
If oral description is used to guide someone to a location, then no additional GPS device is needed, but the guide process becomes inefficient and time-consuming
Solution Approach 1:
The patent replaces the mechanical/oral communication method with an electronic digital transmission system. Instead of verbally describing locations, the system automatically captures, transmits, and displays mark images electronically, substituting the slow oral description process with rapid digital image transfer that instantly conveys location information.
Solution Approach 2:
The system performs preliminary actions by automatically capturing the mark display from the first device before transmission is needed. The mark image is ready-prepared and can be instantly transmitted when guidance is required, eliminating the time needed to manually describe or locate the position during the guidance interaction.
3Loss of information
If mark image is transmitted between devices, then visual location sharing is achieved, but screen resolution and size differences cause display inconsistency
Solution Approach 1:
The patent implements dynamic adaptation where the transmitted mark image is automatically adjusted based on the receiving device's screen characteristics. The system dynamically resizes and repositions the mark display to match the specific resolution, size, and aspect ratio of each device, ensuring consistent visual presentation across different hardware configurations.
Solution Approach 2:
The system changes display parameters such as image resolution, scaling factor, and position coordinates to accommodate different device specifications. By adjusting these parameters based on the receiving device's capabilities, the patent maintains visual consistency of the mark display across devices with varying screen properties.

AI summary
A synchronizing method and a system for marks on electronic maps and a recording medium using the same are provided. In the present synchronizing method, an input signal is received by a first electronic device, so as to draw a mark on the electronic map displayed thereon. The mark is then converted into positioning information of a plurality of positioning points on the electronic map and transmitted to a second electronic device via a wireless transmission network, wherein the positioning information is used for drawing the positioning points on the electronic map displayed on the second electronic device so as to reconstruct the mark. Accordingly, the mark on the electronic map of both communication ends can be synchronized.
